Highly Magical
These species are inherently and instinctively capable of magic and formed by it.
There are magicians, or beings that inherently are capable of magical feats. The concept of magic is well known, although those who cannot wield it exist. These species are naturally more resistant to the influence of the reflection than those with lower magical capabilities. Because magic is inherent and instinctual to them, they can resist outside sources of magic well. Their prime matter is unlikely to be changed. On the flipside, their features can glitch onto other species.
